HARROVV-CART.

Specification of Letters Patent.

Patented Jan. 12, 19115.

Application filed February 20, 1914. Serial No- 820,010.

To all whom it may concern Beit known that I, JOSEPH J. S. OCON- nor, a citizen of the United States, residing at Burbank, in the county of Clay, State of South Dakota, have invented certain new and useful Improvements in Harrow-Carts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to agricultural implements and has special reference to a riding attachment for harrows.

The principal obj cct of the invention is to provide a simple and improved single wheel vehicle which may be readily attached to a barrow and which is provided with a seat for the operator so that the fatigue of walking behind a harrow is eliminated.

A second object of the invention is to provide improved turning means which will enable the vehicle to follow the path of the barrow without undue strain.

lVith the above and other objects in view the invention consists in general of certain details of construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings, like characters of reference indicate like parts in the several views. andz-Figure 1 is a side elevation of the device. Fig. 2 is a plan view thereof. Fig. 8 is a rear elevation thereof. Fig. 4 is a detail section showing the rear scraper and pedal arrangement. Fig. 5 is a detail section taken on the center line of the king bolt. Fig. 6 is a detail showing certain spring arrangements used in connection herewith. Fig. 7 is an enlarged horizontal section through the king bolt showing the turning circle. Fig. 8 is a detail view through the axle.

In the present embodiment of the invention there is provided a frame which consists of the side members 10 and rear member 11. Depending from the side members 10 are the bearing boxes 12 wherethrough passes a shaft 13 having on its ends the nuts 14 so that the shaft can freely revolve in the bearings. Revolubly mounted on the shaft 13 is a wheel 15 which forms the supporting wheel of the vehicle. This wheel is preferablv of the type having a concave rim.

Connecting the forward ends of the side members 10 is a bracket 16 the lower member of which is preferably straight while the upper member has a slight camber and is provided centrally with a lug 17 on which fits the lower end of the spring steel seat arm 18. Secured to the upper end of this seat arm is a seat 19 and to this upper end is also secured the brace frame for the seat. This brace frame consists of side members 20 extending down through suitable brackets 21 bolted or otherwise secured to the side members 10 so that as the seat rises and falls these members 20 slide up and down in the brackets. In order to normally hold the seat in raised position and yet permit this rising and falling action these members 20 are surrounded by the spiral springs 22 which bear against suitable collars on the side members and on the top of the brackets 21. Bolted to the lower end of the member 18 is the foot rest 23. Extending through the bracket 16 is the king bolt 24 and on this king bolt is pivoted the arm support 25. Surrounding this arm support is a brace member which consists of a bar having a circular po tion 26 and forwardlv extending legs 27. The circular portion 26 is concentrio with the king bolt and lies between the upper and lower members of the bracket 16 so that it cannot tilt. At 28 are the attaching arms which are preferably formed of angle iron and which are secured to the parts 25 and 27 bv means of suitable bolts 29. These attaching arms are bent down at their forward ends as indicated at 30 for the purpose of attaching the barrow the eto.

In order to normallv hold the attaching arms in proper position relati e to the frame members 10 there is provided at each side of the forward end of the frame a bracket 31 whereto is pivoted a rod the free end of which is slidablv mounted in a bracket 33 carried on a respecti e member 28. On the rod 32 is a snrinc 34- wh -ch bears against the bracket 33 at one end and against a collar 35 mounted on the rod 39. and adjusted thereon to tension the s rings equally and hold the parts normally in central alinement. This collar is locked on the rod by the set screw 36. Depending from the rear end of the main frame are brac ets 37 wherein is iournaled a rock shaft 39 having mounted thereon a scraper 39. This rock shaft is provided with an arm 40 which is connected by means of a link ll with a pedal lever 42 pivoted to one of the frame members 10, thus the scraper may be placed in contact with the rim of the Wheel or allowed to hang free. By this means the de vice may be used in muddy weather as well as in dry Weather.

From the foregoing it will be seen that the device is so arranged that the operator harrow without unpleasant jerking. I Fun thermore the ring or fifth wheel circle 26 will prevent any tilting of the ground wheels to one side or the other, thus maintaining the'harrow frame in an upright position.

There hasthusbeen provided a simple and efficient device of'the kind "described and of the character specified.

It will I be obvious that many minor rchanges maybe made inthe-form and con- 'struction of this 'invention'without departingfrom the material principlesthereof. It iswnot therefore'desired to confine the inventiontotheexzict form herein shown and described, but it isw-ished to include all such as come properly'within the scope claimed.

Having thus described the invention, what is claimed as new, 1s:

1. In-a device of the'class "described, a

' main frame, a' bracket at the. forward end of Copies-011m: patent'may be obtained for the main frame, a king bolt passing vertically through said bracket, a pivot member on said king bolt, a fifth wheel member surrounding said pivot member, and arms secured to the pivot member and fifth wheel member and extending forwardlyfrom the frame.

2. In a device of the class described, a main frame, a bracket at the forward end of the main frame, a king bolt passing vertically through said bracket, a pivot member on said king bolt, a fifth Wheel member surrounding said pivot member, arms secured to'the pivot memberand fifth wheel member and extending forwardly from the frame, and yieldable means for holding said arms in alinement with said frame.

'3. In a device of the class described, a main frame, arms pivoted to the forward end of the main frame to swing in a horizontal plane, rods each pivoted to a forward corner of the main frame, brackets on said arms receiving the free ends 'of'said rods, collars on said rods, and springs surrounding said rods and'bearing against said collars and brackets.

In testimony whereof, I affix mysigna- J Witnesses:
